To all whom it may concern:

Be it known that I, CALVIN A. SHIVE, citizen of the United States,residing at Payson, in the county of Lincoln and State of Oklahoma, haveinvented certain new and useful Improvements in Gearing forWashing-Machines and the like, of which the following is aspecification.

This invention relates to washing machines and my object is to produce awashing machine embodying a perforated drum and automatic means forcooperating with the operator in oscillating the drum. 7

A further object is to produce a drum composed of a body portion and twodoors disposed at, diametrically opposite points, one of which isdetachable so that when it is removed and the other door is open, accessmay be conveniently had to clean thetub or receptacle without removingthe drum,

A still further object is to produce a machine of the character outlinedwhich embodies the desirable features of simplicity, strength,durability and cheapness of construction.

With these general objects in view the in vention consists in certainnovel and peculiar features of construction and organization ashereinafter appears; and in order that it may be fully understoodreference is to be had to the accompanying drawing, in which e 1 Figure1, is a side elevation of a washing machine embodying my invention. Fig.2, is a vertical section taken on the line II-II of Fig. 1; Fig. 3. is asection taken on the line III-J11 of Fig. 2, Fig. 4c, is a perspectiveview of a part of the drum. Fig. 5, is a side elevation of a modifiedconstruction of the machine.

In the said drawing, 1 indicates a tub or receptacle of substantiallysemicylindrical form mounted upon supporting legs 2 and provided with adrain hole 3 normally closed by a plug 4, the cover 4* being of archedform and hinged as at 4' to a cross bar 4 secured to and bridging oneend of the tub or receptacle. Arranged within this tub or receptacle isa preferably cylindershaped drum consisting of a body 5 havingperforations 6 in its periphery, and the latter. corrugated as at 7,though if the drum is made of wood as indicated, the corruga tions bypreference will only be on the inside as shown in Fig. 3, most clearly,the

end portions of the drum being also corrugated by preference as shown at8. 9 and 10 indicate segment-shaped doors which fit agamst oppositeedges of the end-portions of the body so as to conjointly form therewitha complete cylinder, the peripheral or curved portions of doors 9 and 10being perforated at 11 and 12 respectively, the end portions of saiddoors being likewise corrugated by preference, as'at 16. The door 9 ishinged at 17 to the body of the drum and is equipped with a pin 18 to beengaged by a hook 19 pivoted to the body. The door 1 is provided withhinge-hooks 20 for pivotal and detachable engagement with pins 21projecting from brackets 22 secured to the body and at its free end isprovided with a pin 23 to be engaged by a hook 24 pivotally carried bythe body. When the hooks 2 1 are disengaged from pins 23, door 10 can beswung open and if desired, can be detached from hinge-pins 21 by anobvious manipulation of the door.

25 are spider brackets secured to the endportions of the body 5 andprovided with outwardly-projecting cylindrical trunnions 26 which extendthrough bearing brackets 27 secured to'the side walls of the tub orreceptacle, and secured upon the end of one of the trunnions is a smallexternal-tooth gear-wheel 28 which fits within and meshes with aninternal-tooth gear-wheel 29 journaled on a stub-shaft 30 securedrigidly to the tub or receptacle vertically above wheel 28, and securedrigidly to said wheel 29 is a handle or lever 31.

32 is a pin projecting outward from gearwheel 29 in line with handle 31and pivoted on said pin is a link 33, a spring-cotter 34 extendingthrough said pin to hold the link in position thereon.

35 1s a pair of retractile springs secured at their neighboring ends toopposite ends of link 33 and at their opposite ends to the outwardlyprojecting arms 37 of a pair of angle brackets 38, embracing the cornersof the tub and secured rigidly to the same by screws 39.

The springs are of substantially equal strength and therefore normallyhold the handle 31 projecting vertically upward and the drum with itsdoor 9 uppermost. With the parts arranged as described the door 9 can beeasily opened and the articles 40 to be washed dropped into the drum.Boiling swinging the handle water, containing a suitable washingcomerator then grasps the handle and rocks the same in an obviousmanner, preferably far enough toward each side to move the contents'ofthe drum approximately to the position shown in dotted lines, Fig: 3, itbeii g understood that when the handle is swung toward one side ittensions the retractile spring at the correspondingside'and permitstheother spring to relax, the oscillation of the drum, of course, beingeffected through the turning of the small" gear-wheel by the large onesecured to the handle. A. comparatively slow movement of the handleimparts rapid movement to the drum, so that the articles therein shallacquire suflicient momentum by the time they are raised to the-positionshown in dot ted lines, Fig. 3, to be proj ected'in the directionindicated by the arrow, same figure,-to

the opposite side of the drum. The articles will impinge upon'such sidewith sufficient force to continue therotation of the drum for a slightdistance without further effort on thepa-rt of the operator,- thiscontinued rotation continuing the movement of the handlein the samedirection and increasing the tension of the tensioned-spring, whichspring immediately retracts'so" as to start 7 the reverse oscillation ofthe drum and handle, this reverse operation being assisted by theoperators pressure or pull on the handle. YVhen. the drum'has beenrotated in said reverse direction the proper distance, incidentallytensioning the originally relaxed sprin and permitting the originallytensione spring to relax, the articles through the momentum acquiredjump to the opposite side of the drum and thus increase the extent ofsuch reverse operation and the tension of the spring-originally relaxed,all subsequent operations being repetitions of those described. From theforegoing itwill be apparent that the actual'labor entailed ontheoperator is small, asthe articles'being washed are utilized byinereasing'the' tension of the springs alternately, to" cause saidsprings to react strongly and thus perform the actual reversingoperation of' the drum, and leave the operator the duty only ofcontinuing such operation for a suitable distance in each direction. V

r If desired tovclean the tub or receptacle after the Washed articlesare removed and the water has been drained from the tub, the handle 31is turned" until the door 10 is uppermost to permit such door to bedetached from the drum. -The handleis then released and the tensionedspring retracts and revolves the drum back to its original position withthe door 9 uppermost, which mally exposed screws 38- disposed by Fig; 1the.

door, is then opened and the'operator given access to the bottom of thetub or receptacle I through the drum. p

For convenience in. removing the drum from the receptacle, the arms ofthe spiderbrackets 25 are'of such length as to project above the tub orreceptacle as shownclearly. in Figs. 1' and 2, so that the screwsfastening said spiders to are conveniently accessible. After the northebody of the drum are removed, the V handle is manipulated to turn thedrum one- 7 half revolutionso as to exposethe other two" screws, aswillbe readily understood By reversing these operations the drum can beresecuredinthe tub.- I In the preferred'construction disclosedib'y Fig.5, the springs 35 arearranged' at diametrically opposite sides of" gearwheel 29 and attheir inner ends areattached to links 33* pivoted to saidwheel at po n diametrically opposite from eachother and equal distancesf'rozn'the handle 31, of the springs beingattached to thebrackets in thehorizontal plane of" the axis of said'jwheel. When the handle-21 isoperated both springs 35 "ofi'er a yielding resistance and when thesprings cohperate in returning andhence the drum to normal position. Bythis construction it ispractical'to employ springs of" approximatelyhalf the strength of the springs employed in the construction shown byFig. 1 asin the last-named? con stru'ction, the springs'alternatelyoffergyield ing. resistance to the operation of the-handle the outerends 7 handle is released said 7 the handle and do not co'ciperate inreturning-thehandle V to normalposition, t 7

Referring now tofFig; 5, it will beseen that thefsprings 35* arearrangedin the hori-r zontal plane of'the axis oflwheel' 29' and are q fpivotally connected at their .inn'er'endsto said wheel and proj ectingjarms '37 of brackets 38-,"which in this figure are; disposed in a higherplane than in Fig, 1. This arrangement'of parts permits the use oflighten'or weaker springs, as the:springscohperate in resisting movementof the handle awayfro'm avertical positionand in'returningthe handle tosuch tion shown by Fig. f where each spring re- 7 sists movement of the'handle away from the vertical and then" assists in drawingfit back tosuch" vertical position; With the tains' an impetuswhich assists theoperator atdiametricallyfopposite p i t V at. their outer :endsto theoutwardl '1'10' position asdistinguished from the construe inovercomingthe resistance of the springs without exertion. In theconstruction shown p osed'sudd'enly at'times to make the operaresistanceof thespringsi's im- V 7 From the above description it will be apparentthat I have produced a washing machine embodying the features ofadvantage enumerated as desirable and which is susceptible ofmodification in some particulars without departing from the principle ofconstruction involved. 7

Having thus described the invention what I claim as new and desire tosecure by Let ters Patent, is z- A gearing for washing machines and thelike, comprising a suitable support, a ro tatable object journaled onsaid support connected axially thereto a gear, an internally-toothedgear wheel disposed eccentrically of and inclosing and meshing'withCopies of this patent may be obtained for five cents each, by addressingthe said gear, a handle secured to and projecting from said gear wheelwhereby to oscillate the same, a link pivoted on said gear wheel at apoint in line with said handle, and a pair of retractile springsconnected at their opposite ends to said link and said supportrespectively and adapted to maintain said wheel with its handle normallyin vertical position.

In testimony whereof I aflix my signature, in the presence of twowitnesses.
